[Solved] Cannot change to One-page Checkout

[Jon T]

I have recently upgraded to PS 1.5.4.1 from 1.2.5.0 and cannot change Order Preferences->General-> Order Process Type to "One-page Checkout". After clicking Save I get the message "The settings have been updated successfully" but after navigating away from the page and back again the setting is unchanged.

 

I have tried to Force Compile the Smarty cache but it has made no difference. In fact, I think the Smarty settings are not updating too! I contacted the host to ask them to enable the Memcache PECL extensions to see if that might help but they wont because its on a shared account.

 

Are there any other solutions that I can try?

 

Thanks

you should check the PS_CONFIGURATION table

 

search there field:

PS_ORDER_PROCESS_TYPE

 

make sure that it isn't duplicated there, if it is - just remove duplicated value

Hi Vekia,

 

That's it! I couldn't find the duplicates at first until I sorted on PS-CONFIGURATION: name.

 

There are duplicates of other rows too which I believe happened when I performed an upgrade.

 

Many thanks for your help.
